The chk_bkdb.pk3 file you have requested: Maps / Deathmatch / CHK BKDB - 1.78mb is not available. Perhaps try browsing all files for the game Soldier of Fortune II and upload any files you want to share or are missing. This is the only information we could locate:
Setting takes place in a mining area. Lot's of underground tunnels and stuff. Map has a large outside area with lots of little hills and foilage which I'm assuming the author intended to do because I could not find any health packs, or other weapons on the map besides the MSG91A1 Sniper Rifle.
